Not counting narrator Cecilia Roth, Tequila band members are credited in alphabetical order by first name (Alejo Stivel, Ariel Rot, Felipe Lipe, Julián Infante and Manolo Iglesias). After them, the rest of the cast too are ordered by first name.
At the point of the movie premiere, three Tequila band members still alive. Manolo Iglesias died in 1994 and Julián Infante in 2000, both by AIDS. Hence Iglesias and Infante only appear as archive footage. The documentary pays tribute to them.
One of the strong points of the documentary is The Spanish Transition and the later arrival of The Madrilenian Scene (known in Spain as "La Movida Madrileña"). The Spanish Transition was the process happened in Spain with the end of General Francisco Franco's dictatorship and the return to the democracy, after fascist coup d'etat on July 18, 1936, which caused Spanish Civil War that ended on April 1, 1939, turning the country to the dictatorship with Franco as dictator. Franco's death on November 20, 1975, caused an inner transformation in Spain noticeable especially in fashion style, cinema and music, after the missing of the censorship. Eventually, it led to The Madrilenian Scene (previously so-called Spanish New Wave), a sociocultural movement where singers and music bands claimed freedom and wanted experiment new sounds after 40 years of Francoist repression.
